OnAir USB HDTV-GT Portable HDTV Tuner
It’s a well known secret; I guess then that it’s not really a secret, that you can get HDTV broadcasts over the airwaves. That’s right; if you have an HDTV tuner you can pick up many of the local stations that broadcast in High-Def. If you’re a mobile type and travel a lot and you want to watch HDTV broadcasts anywhere with an HDTV signal, you are in luck. AutumnWave’s OnAir HDTV-GT lets you connect an HDTV tuner to your laptop or PC with a USB connection.
The HDTV-GT features a remote control and DVR features so you can record and watch your High-Def shows any time you want. A rather surprising feature is that the HDTV-GT allows you to receive QAM signals, the unencrypted cable signals that cable companies sometimes use to broadcast local stations.
The HDTV-GT comes with a tuner application that allows the user to time shift programming with the built in DVR feature. Users can also schedule recording of up to 80 shows. The unit can also record while playing back other programming. It also allows the streaming of HD files in ATSC formats. It also tunes in regular television channels (NTSC) when there is no digital goodness.

The HDTV-GT has the capability to show program guides (EPG). It has a SPDIF output for output to an AAC compatible sound card. The unit is powered by the USB connection so there is no need for batteries, except for the remote.
The HDTV-GT does have a downside. The remote control is rather large. For a mobile device such a large remote control definitely hinders storage and portability.
